tests: Add CPU switching tests
This changeset adds a set of tests that stress the CPU switching code. It adds the following test configurations: * tsunami-switcheroo-full -- Alpha system (atomic, timing, O3) * realview-switcheroo-atomic -- ARM system (atomic<->atomic) * realview-switcheroo-timing -- ARM system (timing<->timing) * realview-switcheroo-o3 -- ARM system (O3<->O3) * realview-switcheroo-full -- ARM system (atomic, timing, O3) Reference data is provided for the 10.linux-boot test case. All of the tests trigger a CPU switch once per millisecond during the boot process. The in-order CPU model was not included in any of the tests as it does not support CPU handover.
